Maybe you should get a decent PvP rating before giving advice in a condescending tone. Additionally, nobody is impressed by Noun + Noun = Noun posting equations.
warlocks problems for pvp are the lack of burst, escape, or mitigation. Tagging SL to corruption won't make it OP.
You must only play affliction? Gnome Destro Lock = Burst + Teleport + Escape Artist + DeathCoil + Shadowfury + HowloTerror + Fear
Mitigation = Soul Link
What more could you ask for? I personally have no problem in PvP. Maybe you should try a different pvp spec.
